Ukuhlela Incazelo Yomkhiqizo
Igama lesiNgisi elithi Acrolonitrile (Proprnr nitile; Vinyl cyanide)
Isakhiwo kanye nefomula yamangqamuzana CH2 CHCN C3H3N
Indlela yokukhiqiza yezimboni ye-acrylonitrile ngokuyinhloko iyindlela ye-propylene ammonia oxidation, enezinhlobo ezimbili: umbhede omanzi kanye nama-reactors ombhede ongashintshi.Ingabuye yenziwe ngokuqondile kusuka ku-acetylene ne-hydrocyanic acid.
Izinga lomkhiqizo elingu-GB 7717.1-94
Ukusetshenziswa kuyingxenye ebalulekile yamakhemikhali aphilayo, okuwumthako obalulekile wokukhiqiza imicu yokwenziwa (imicu ye-acrylic), irabha yokwenziwa (irabha ye-nitrile), nezinsalela zokwenziwa (i-ABS resin, i-AS resin, njll.).Ibuye isetshenziselwe i-electrolysis ukukhiqiza i-adiponitrile kanye ne-hydrolysis ukukhiqiza i-acrylamide, futhi iyimpahla eluhlaza yokukhiqiza imikhiqizo yamakhemikhali efana nodayi.
Umhleli Wokupakisha kanye Nesitoreji Nezokuthutha
Ipakishwe emigqomeni yensimbi ehlanzekile neyomile ezinikele, enesisindo esiwu-150kg isigubhu ngasinye.Isitsha sokupakisha kufanele sivalwe ngokuqinile.Iziqukathi zokupakisha kufanele zibe nezimpawu “ezivuthayo”, “ezinobuthi” kanye “neziyingozi”.Kufanele igcinwe endaweni eyomile nengena umoya, enezinga lokushisa elingaphansi kuka-30 ℃, engenalo ilanga eliqondile, futhi ihlukaniswe nemithombo yokushisa nezinhlansi.Lo mkhiqizo ungathuthwa ngemoto noma ngesitimela.Landela imithetho yezokuthutha "yezimpahla eziyingozi".
Ukusetshenziswa kwezinyathelo zokuphepha ukuhlela
(1) Abaqhubi kufanele bagqoke izinto zokuzivikela.Ngaphakathi kwendawo yokusebenza, ukugxila okuphezulu emoyeni ngu-45mg/m3.Uma isakazeka ezingutsheni, susa izingubo ngokushesha.Uma uchaphazwe esikhumbeni, hlambulula ngamanzi amaningi.Uma uchaphazekile emehlweni, hlambulula ngamanzi amaningi okungenani imizuzu engu-15 futhi ufune usizo lwezokwelapha.(2) Akuvunyelwe ukugcina nokuthutha kanye nezinto ezine-asidi ezinamandla njenge-sulfuric acid ne-nitric acid, izinto ezine-alkaline njenge-caustic soda, i-ammonia, ama-amine, nama-oxidants.
